' 8 Claims. (01. 16085) My invention relates .to combination sliding androlling light screens such as window shades, curtains or blinds and hasparticular reference to window shades or the like slidably mounted on asupport and having overlapping spaced portions provided with spacedopenings such that sliding of the shade on its support permits thepositioning of the spacedopenings inone portion in various relationshipswith similar openings in the other portion as, for example, tointerceptdirect sunlight while permitting vision and ventilation or, forexample, to provide complete interception of light and at the same time,if desired, to roll up in use as an ordinary window shade, door or porchscreen.

My invention .is notlimited to but has particular reference to the useof tough, opaque paper sh'ades or the like, cheap to make, easy to cleanand readily disposed of and replaced when faded,

though any suitable material may be used. A

shade embodying my invention not only is slidable on its support,preferably the usual spring type window shade roller, but may be rolledup like any window shade, in which case the two hanging, overlapping,spaced portions become adjacent, like a double thickness of shade, rollup together as little or as far as desired and in such manner that theadjacent hanging portions coact to make an opaque shade, the diameter ofthe roller being such that when the two hanging portions come togetherthe openings of one portion are closed by overlapping opaque spaces ofthe other portion (Fig. 4)

Among the objects of my invention is the provision of a satisfactorylight screen of .low cost which permits ventilation and shuts out directsunlight, as desired. Another object is the provision of an easily hungshade, readily cleaned or replaced. Still another object is to provide adesirable form of shade not easily pulled from its support and which issimple to install.

With the foregoing and other objects in view, as will be apparent tothose skilled in the art as the description proceeds, my inventionresides in the combination and arrangement of parts and in the detailsof construction described in this specification and particularly pointedout in the appended claims, it being understood that changes may be madein the particular embodiment of the invention within the scope of whatis claimed without departing from the spirit of the invention. I intendno limitation other than those of the claims when fairly interpreted inthe light of the full disclosure and the present state of the art.

In the drawing, Fig. 1 is afragmentaryassembly view illustrative of apreferred embodiment of my inventionincluding the usual shade roller,- aperforated slotted shade slidably mounted on said roller and a pullcord-to actuate said roller; Fig. 2 is an end view of the assembly ofFig. 1 without the pull cord; Fig. 3 is a fragmentary viewillustrativeof the-shade of Fig. '1; Fig. 41s an end view similar toFig. 2 as the shade is starting to roll up; Figs. 5 and 6 illustratemodifications of the assembly of Fig. 1. Similar eference charactersrelate to similar parts in all views.

Turning first to the shade illustrated in Fig. 3, this may be a singleor composite sheet of thin,

tough, flexible and, preferably, opaque fibrous,

woven, or flowed material such as paper, sheet plastic, cloth or othersuitable material. I prefer a suitable opaque paper which can be cleanedand is readily and cheaply replaced if faded or a change is desired, asfor a new color scheme. Preferably it is somewhat greater than twice thelength of the light openin it is to shade. It may be provided with oneor more longitudinal slots Ill, It, for the reception of and guidance ona fastening member or members 9, 9, (Fig. 1).

At either end of thc slots In there are portions of the shade perforatedwith, in this case, long, narrow, transverse openings 8, 8, regularlyspaced, the space between the openings preferably being slightly widerthan the openings in order that when the shade is rolled the openings 8,8, may be overlapped (Fig. 4). The two portion of the shade aresymmetrical with respect to the slots l0, l0.

In some instances it may be desirable to provide a composite shadestructure'as in Fig. 5, for example, comprising a slotted portion 5 andflexible tapes 4, 4, to the number desired connected thereto, said tapescarrying slats 3, 3, of any suitable, preferably opaque, materialfastened to the tapes to provide regularly spaced and paralleltransverse openings 2, 2, or the tapes themselves may be provided withguiding slots I, l, as in Fig. 6.

The shade, however constructed, may be hung from any suitable supportbut preferably is draped or hung over the usual shade roller 1 andslidably connected thereto by tacks 9 or the like. If desired, a pullcord 6 (Fig. 1) may be provided to actuate the spring roller but eitherhanging portion of the shade may be pulled to release the roller springas is done with any window shade. The space at the top of the dependingportions maybe and preferably is of such length compared with the sizeof the roller 1 that when the curtain is rolled up (Fig. 4) the openingsin one portion will be blacked out by the opaque material of the otherportion and the shade, rolling up double, may be used like any otherwindow shade.

In use, the ordinary shade roller or other support may be slippedbetween the hanging portions of the shade, tacks 9 or other suitablefastening devices positioned in the slots l and the shade roller put upin suitable brackets, such as the present shade brackets, for example.Thereafter the shade may be rolled up and down in the usual way but whendrawn down completely over a part or all the window, door, or otherlight opening, the shade will hang double, the portions spaced, and itmay be slid back and forth over the roller, guided by the slots ID, inorder to position the openings of one hanging portion as desired withrelation to the openings of the other, hanging portion.

-What I claim is:' A I 1. .As an article of manufacture, a shadecomprising symmetrical portions spaced from each other. and eachprovided with spaced openings and in the space between said portionsprovided with one or more slots extending longitudinally of the shadeadapted for the passage therethrough of fastening members.

2. As an article of manufacture, a shade comprisingga body of thin,flexible and substantially opaque material provided with at least oneslot extending longitudinally of the shade and portionsat the ends ofsaid slot symmetrical with respect thereto and each provided With aseries of spaced and similar openings extending transversely of theshade and parallel to each. other, the space between said parallelopenings being at leastfas great as thewidth of said openings.

7 3. A shade comprising similar portions hanging down on each side of asupport and spaced from each other, each said portion being providedwith regularly spaced openings extending transversely of the shade andparallel to each other, the space between said parallel openings beingat least as great as the width of said openings and means to slidablyconnect said shade to said support to facilitate the alignment of thetransverse openings in one portion of said shade with respect to thetransverse openings in the other portion thereof.

4. A structure as defined in claim 3 in which said slidably connectingmeans facilitates the alignment of the spaced openings of one saidportion with the spaces between the spaced openings of the other portionwhen said shade is unrolled.

5. As an article of manufacture, a shade comprising a body of flexiblematerial provided with slots and portions at either end of said body ofmaterial connected therewith and symmetrical with respect thereto andeach provided with a series of spaced and similar openings at rightangles to said slots and parallel to each other, the spacebetweensaidparallel openings being greater than the width of said openings and ofsubstantially opaque material.

6. A structure as defined inclaim 5 in which said portions are connectedto said body of flexible material by means including a tape member andsaid portions comprise slats of opaque material connected to said tapemember.

' '7. A shade provided with similar portions, each said portioncomprising a series of spaced and parallel and substantially opaquemembers and means to mount said shade comprising a flexible memberprovided. with atleast' one slot at right angles to said opaque members.i

8. A shade doubled upon itself over a support and otherwise free andcomprising two 'dependent like portions connected only at their adjacentends and downwardly projecting in parallel planes, each of said portionsbeing provided with a series of spaced and similar openings extendingtransversely of .the shade and means to slidably connect said shade tosaid support.
